Measuring open source software success

Since the mid-1990s, there has been a surge of interest among academics and practitioners in open source software (OSS). While there is an abundance of literature on OSS, most studies on OSS success are either qualitative or exploratory in nature. To identify the factors that influence OSS success and establish generalizability, an empirical study measuring OSS success would enable OSS developers and users to improve OSS usage. In this study, we develop an OSS success model from a previous Information Systems success model incorporating the characteristics of OSS. Using the proposed model, we identify five determinants for OSS success as well as a number of significant relationships among these determinants. Our findings demonstrate that software quality and community service quality have significant effects on user satisfaction. Software quality and user satisfaction, in turn, have significant effects on OSS use. Additionally, OSS use and user satisfaction have significant effects on individual net benefits. This research contributes towards advancing theoretical understanding of OSS success as well as offering OSS practitioners for enhancing OSS success.     

Student union ‘political anti-politics’ in post-conflict Nepal

In contrast to rhizomatic youth movements that inspired the ‘Arab spring’ uprisings and the ‘Occupy’ movements, youth political activism in Nepal was orchestrated by hierarchical political parties in part through political student unions. The ability of parties to deploy youth into the streets to enforce general strikes and force election participation has been critical to their success, but focus groups conducted with Nepali students in the spring of 2013 suggest that many youth are withdrawing from party activism. Youth disengagement in Nepal is the product of years of political instability and conflict that has impeded peace and development, rather than a globalizing individualism that is fragmenting traditional institutions. In this paper, I argue that the ability of political parties to mobilize youth in post-conflict Nepal is being challenged by two related conditions. First, the demands of political parties on students for personal sacrifice are weighed by students against their own personal aspirations and, secondly, the inability of the party hierarchies to sacrifice their priorities for greater political stability, development and peace – exemplified by the repeated failure to resolve constitutional issues – made this commitment to personal sacrifice harder to justify.     

Avian diversity in a suburban park system: current conditions and strategies for dealing with anticipated change

A growing trend towards increased urbanization emphasizes the role of suburban parks in wildlife conservation. Spatial planning aimed at maintaining biological diversity and functionality must consider how changes at landscape and more local scales will influence the biotic structure of urban areas. From May 2006 to July 2010, bird surveys were conducted in three metropolitan parks in Cleveland, Ohio, USA. Surveys were conducted with the goal of examining the effect of vegetation structure and adjacent land cover on the distribution and species richness of breeding birds within this park system. A total of 65 species were recorded throughout the study area. Avian species richness was linked to several habitat metrics, measured at both the local and landscape scale. Generally, species richness was highest at locations characterized by moderate forest cover. The proportion of canopy cover at survey sites related negatively to species richness and the density of understory vegetation showed a positive relationship with species diversity. Despite the influence of these three metrics, sensitivity analysis indicates that the density of understory vegetation is the most significant correlate to avian diversity within this suburban park system. Management actions aimed at providing habitat for the greatest diversity of breeding songbirds within the study area should allow for moderate canopy cover while retaining or improving the structural complexity of understory vegetatation.     

Are Social Innovation Paradigms Incommensurable?

This paper calls attention to the problematic use of the concept of social innovation which remains undefined despite its proliferation throughout academic and policy discourses. Extant research has thus far failed to capture the socio-political contentions which surround social innovation. This paper therefore draws upon the work of Thomas Kuhn and conducts a paradigmatic analysis of the field of social innovation which identifies two emerging schools: one technocratic, the other democratic. The paper identifies some of the key thinkers in each paradigm and explains how the struggle between these two paradigms reveals itself to be part of a broader conflict between neoliberalism and it opponents and concludes by arguing that future research focused upon local contextualised struggles will reveal which paradigm is in the ascendancy.     

A reappraisal of Delphi 2.0 for public relations research

This paper introduces, analyzes, and explains the Delphi method of research, particularly as it applies to the public relations industry. The Delphi technique became known some 50 years ago when the RAND Corporation used it for forecasting. Since then, scholars and forecasters have used it periodically for qualitative explorations into complex issues or domains. The overall purpose of the Delphi is to facilitate formal discussion among selected experts in a given domain around a particular topic; it is particularly useful when those experts cannot easily gather in one place. The method encourages the sharing of diverging worldviews over a few “rounds” or iterations in the hope that the views may converge into some direction around the given topic. For this reason, the Delphi has often been used in situations or environments that tend to be somewhat ambiguous and where interviews and surveys are neither timely nor appropriate.     

Safety sans Frontières: An International Safety Culture Model

The management of safety culture in international and culturally diverse organizations is a concern for many high‐risk industries. Yet, research has primarily developed models of safety culture within Western countries, and there is a need to extend investigations of safety culture to global environments. We examined (i) whether safety culture can be reliably measured within a single industry operating across different cultural environments, and (ii) if there is an association between safety culture and national culture. The psychometric properties of a safety culture model developed for the air traffic management (ATM) industry were examined in 17 European countries from four culturally distinct regions of Europe (North, East, South, West). Participants were ATM operational staff (n = 5,176) and management staff (n = 1,230). Through employing multigroup confirmatory factor analysis, good psychometric properties of the model were established. This demonstrates, for the first time, that when safety culture models are tailored to a specific industry, they can operate consistently across national boundaries and occupational groups. Additionally, safety culture scores at both regional and national levels were associated with country‐level data on Hofstede's five national culture dimensions (collectivism, power distance, uncertainty avoidance, masculinity, and long‐term orientation). MANOVAs indicated safety culture to be most positive in Northern Europe, less so in Western and Eastern Europe, and least positive in Southern Europe. This indicates that national cultural traits may influence the development of organizational safety culture, with significant implications for safety culture theory and practice.     

Unions and the structure of earnings inequality: Cross-national patterns

We examine differences in the structure of earnings inequality for men in four advanced western industrialized nations that differ in the nature and extent of unionism: the United States, Canada, Norway, and Sweden. We argue that the economic effects of unionism depend on whether (1) the bargaining structures of labor markets are centralized or fragmented; and (2) the political organization can be characterized as a corporatist or a pressure-group system. We find some support for our principal hypotheses that cross-national differences in systems of collective bargaining and political institutions affect the size of the earnings gap between male union and nonunion members, as well as the extent of wage dispersion among unionized workers.
